I worked as a full-stack developer specializing in MERN stack, Next.js, and Shopify development, delivering scalable e-commerce platforms and automation-driven backend systems. My responsibilities included building custom Shopify themes, converting Figma designs into responsive storefronts, developing custom Shopify apps using Polaris React, and implementing Buy-For-Me systems with fully separated backend logic. I designed advanced pricing engines, multi-vendor order management systems, and inventory automation workflows based on supplier locations. I also developed backend platforms to manage products, orders, inventory, and advertising spend independently from Shopify native orders, allowing businesses to centralize operations and automate processes. Additionally, I integrated Shopify data with social media advertising platforms such as Meta and Google Ads, providing unified performance and analytics dashboards. Technologies used included React.js, Next.js, Node.js, Express.js, Shopify Liquid, Polaris React, MongoDB, PostgreSQL, Firebase, Supabase, and Docker for containerized deployments. I focused on performance optimization, system scalability, and clean architecture throughout all projects.
